BOTTLE-CLOSURE.

Original application filed August'22, 1910, Serial No. 578,430. Dividedand this application Specification of Letters Patent.

Patented Nov. 28, 1911.

filed March 20,

1911. Serial No. 615,697.

To all whom it may concern:

Be it known that I, HUGO TURK, a subject of the Emperor of Germany, andresident of Iserlohn, Germany, have invented. certain new and usefulImprovements in Bottle-Closures, of which the following is aspecification.

This invention relates to bottle closures its object being which allowsof the bottle being rapidly and hermetically closed, and is a divisionof my cooperating application filed Aug. 22, 1910, Ser. No. 578,430.

The accompanying drawings show one form of embodiment ofthe inventionapplied to a tilting bottle and in these drawmgs:

Figure 1 is a front elevation view of a tilting bottle provided with mynew closing device, the latter being shown in a closed state. Fig. 2 isan analogous view of the same, the closing device being in an open statewhile, Fig. 3 shows a perspective side elevation of the bottle and itsclosure.

The tilting bottle 1 is carried by a metal frame formed by a base ring 2uprights 6 and an upper ring 9. It is adapted to oscillate by means ofpivots 1 k in bearings 15 carried by any suitable supporting device 16.

The closing device comprises a plane glass disk 21 which is ground onthe upper fiat edge 22 of the neck 20 of the bottle. This covering disk21 carries in the center of its upper surface a head 23 in which thehorizontal cross shaft 24 the ends of which are secured into the upperends of a sleeve 25, is adapted to rotate. The lower end of said sleeveis closed by a nut cap 26 through which passes a piston rod 27 thediameter of which is smaller than the bore of the sleeve 25. Insertedbetween the bottom of the nut cap 26 and the piston 28 secured insidethe sleeve 25 on the end of rod 27 is a coiled spring 29 which has aconstant tendency to push the piston 27 into the sleeve.

The piston rod 27 is pivotally connected at its free end. with an car 30carried by the ring 9 on each side of the neck 20 of the to provide adevice of this kind' bottle. It will be easily understood that thanks tothis spring carrier the closing disk 21. is yieldingly applied on theedge of the neck of the bottle thus securing an instantaneous and tightclosing of the latter.

hen it is desired to open the bottle, it will do to push the cover 21back by means of the handle 31 with which the head 23 is provided so asto cause it to assume an opened position as shown in Fig. 2, the springs29 holding the cover in this position.

It is needless to say that various modifications of details may be madein the closing device described above. Thus the closing cover instead ofbeing plane and ground on the edge of the neck, may have any othersuitable shape cooperating with a bottle neck having a correspondingshape. The material of which the said closing cover is made may alsovary. It may be hard such as glass, hard rubber, celluloid or any othernon oxidizable material or soft such as supple india rubber.

Having now fully described my said in vention, what I claim and desireto secure by Letters Patent, is:

1. In a bottle closure, the combination of a frame provided withperforated ears, two piston rods pivoted to the ears, pistons on therods, cylinders in which the pistons operate, springs interposed betweenthe pistons and the ends of the cylinders, a transverse rod connectingthe cylinders, and a stoipper pivotally mounted on the transverse r0 2.In a bottle closure, the combination of a ground glass stopper, atransverse rod on which the stopper is rotatably mounted, a frame forsupporting the stopper, a telescopic connection pivoted at each end ofthe rod, a pivotal connection between the opposite ends of thetelescopic connections and the frame, and springs for normally drawingthe stopper toward the frame.

In testimony whereof I have hereunto set my hand in presence of twowitnesses.
